PERFORMANCE ORDER
1. Remove a head of the block of cylinders and put on two wooden supports.
2. Remove camshafts.
3. Remove тарельчатый a pusher.
4. Designate valves before dismantling that at assemblage to establish them on former places. For this purpose number plates of valves a felt-tip pen.
5. Remove valves by means of available натяжителя springs. Thus pull springs and remove crackers of a core of the valve. Then unclench a spring and take the top plate and a valve spring.
6. Remove маслоотражательные caps.
7. Take the valve from a head of the block of cylinders in a direction to the combustion chamber.
8. Clean the valve. Valves with the scorched plate, with small height of a plate, with the worn out and scratched core replace.
9. In repair shop it is possible to check up a valve core on admissible palpation which should not make more than 0,03 mm.
The prevention

Final valves are filled by sodium. They should not be exposed to the soldering or be used as the working tool (for example, as a pusher): danger of explosion!



Installation

PERFORMANCE ORDER
1. Before assemblage of valves check up their directing, if necessary – finish saddles of valves.
The prevention

3. Slightly grease with engine oil a core of the valve and directing the valve and insert the valve.
4. Establish маслоотражательный a cap.
5. Establish a valve spring.
6. Then establish the following valve. Thus do not mix inlet and final valves.
7. Establish тарельчатый a pusher.
8. Establish camshafts.
9. Establish a head of the block of cylinders.
